[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please refer to the following: Figure 1 and Figure 2 , Figure 1 and Figure 2This is a perspective view of the bearing mounting structure of this utility model from different angles in the first embodiment. In this embodiment, the bearing mounting structure 100 includes a mounting shell 101. The mounting shell 101 includes a body 101a and an annular limiting structure 103. In this embodiment, the body 101a is plate-shaped and has a reverse side 101b and a front side 101c. An opening 102 is provided on the mounting shell 101. The annular limiting structure 103 is provided on the front side 101c of the body 101c, and the opening 102 is provided on the inner side of the annular limiting structure 103. Specifically, the annular limiting structure 103 can be detachably connected to the body 101a of the mounting shell 101, such as being detachably mounted to the body 101a of the mounting shell 101 by screws / bolts; or, the annular limiting structure 103 is provided with threads on its outer circumference, and the annular limiting structure 103 is threadedly connected to the inner opening (not shown in the figure) of the body 101a of the mounting shell 101. Alternatively, the annular limiting structure 103 can be integrally formed with the body 101a of the mounting shell 101. In one embodiment, the inner edge 103a of the annular limiting structure 103 near the opening 102 is flush with the edge of the opening 102. In another embodiment, the inner edge 103a of the annular limiting structure 103 near the opening 102 is separated from the edge of the opening 102 by a distance (a first distance). Providing the annular limiting structure 103 at the opening can enhance the structural strength of the opening 102 of the mounting shell 101.
[0030] In this embodiment, the annular limiting structure 103 is provided with a plurality of radial limiting ribs 104 and a plurality of axial limiting structures distributed circumferentially along the annular limiting structure 103. Specifically, in this embodiment, the axial limiting structure is a combination of a threaded post 105 and a screw 108 and / or an axial limiting buckle 106. The radial limiting ribs, the threaded post, and the annular limiting structure are integrally formed. Further, the axial limiting structure can also be integrally formed with the annular limiting structure.
[0031] Specifically, in this embodiment, there are three radial limiting ribs 104, which are evenly distributed circumferentially along the annular limiting structure 103. There are two threaded post 105s, which are symmetrically distributed circumferentially along the annular limiting structure 103. There are three axial limiting buckles 106, which are evenly distributed circumferentially along the annular limiting structure 103. Thus, the radial limiting ribs 104, threaded post 105, and axial limiting buckles 106 are arranged around the opening, with the threaded post 105 symmetrically positioned and the radial limiting ribs 104 and axial limiting buckles 106 spaced apart from each other. The annular limiting structure 103 (or the mounting housing 101 body 101a), radial limiting ribs 104, threaded post 105, and axial limiting buckles 106 together form a space for accommodating the bearing 200 (hereinafter referred to as the accommodating space 107).
[0032] Specifically, in this embodiment, each radial limiting rib 104 stands upright on the annular limiting structure 103 and is generally arc-shaped in the circumferential direction of the annular limiting structure 103. Each radial limiting rib 104 includes a body 104a and abutment portions 104b distributed at both ends of the body 104a in the circumferential direction of the annular limiting structure 103. Compared to the body 104a, the abutment portions 104b are closer to the central axis of the opening in the radial direction. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 As shown, after the bearing 200 is installed on the bearing mounting structure 100, the abutting part 104b abuts against the outer peripheral surface 201a of the outer ring 201 of the bearing 200 to limit the bearing 200 in the radial direction.
[0033] Specifically, in this embodiment, each threaded post 105 stands upright on the annular limiting structure 103, and each threaded post 105 has a threaded hole 105a on its end face away from the mounting shell 101. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 As shown, after the bearing 200 is installed on the bearing mounting structure 100, the shank 108a of the screw 108 is screwed into the threaded hole 105a, and the edge region of the head 108b of the screw 108 extends beyond the threaded hole post 105. Therefore, the lower end of the edge region of the head 108b can abut against the end face 201b of the outer ring 201 of the bearing 200, thereby limiting the bearing 200 in the axial direction and restricting the movement of the bearing 200 away from the mounting housing 101.
[0034] Specifically, in this embodiment, there is a first distance between the radial limiting rib 104 and the opening 102, and a second distance between the threaded hole post 105 and the opening 102. The first distance can be equal to the second distance, or the first distance can be less than the second distance. By setting the distance, the mounting shell 101, the radial limiting rib 104, and the threaded hole post 105 form a receiving space 107 for accommodating the bearing 200.
[0035] Specifically, in this embodiment, the straight-line distance from the threaded post 105 to the center axis of the opening 102 is greater than the straight-line distance from the radial limiting rib to the center axis of the opening. Thus, the threaded post 105 does not restrict the radial position of the bearing 200 when it is installed, making installation easier.
[0036] Specifically, in this embodiment, each axial limiting buckle 106 stands upright on the annular limiting structure 103. The top 106a of each axial limiting buckle 106, away from the annular limiting structure 103, has a buckle portion 106b. The buckle portion 106b extends towards the receiving space 107, making each axial limiting buckle 106 shaped like the number "7". The top of the buckle portion 106b is inclined to allow the bearing 200 to be inserted into the receiving space 107 from above the buckle portion 106b. Please refer to [link / reference]. Figure 3 and Figure 4 As shown, after the bearing 200 is placed into the receiving space 107, the fastening part 106b abuts against the end face 201b of the outer ring 201 of the bearing 200, thereby further strengthening the axial positioning of the bearing 200 and restricting the movement of the bearing 200 away from the mounting housing 101.
[0037] Specifically, in this embodiment, the radial limiting rib 104, the threaded hole post 105, and the axial limiting buckle 106 are all a first distance from the inner edge 103a of the annular limiting structure 103. After the bearing 200 is placed in the receiving space 107, the annular limiting structure 103 supports the bearing 200 in the inner region 103b between the inner edge 103a and the radial limiting rib 104, the threaded hole post 105, and the axial limiting buckle 106, thereby axially limiting the bearing 200 between the annular limiting structure 103 and the head 108b of the screw 108 and the buckle of the axial limiting buckle 106.
[0038] In one embodiment, a raised ring 109 is also provided on the reverse side 101b of the mounting shell 101 body 101a, surrounding the opening 102. The inner edge of the raised ring 109 is flush with the edge of the opening 102. The arrangement of the raised ring 109 and the annular limiting structure 103 enhances the structural strength of the mounting shell 101. In one embodiment, the raised ring 109 and the annular limiting structure 103 are connected on the side near the opening 102, or the raised ring 109 and the annular limiting structure 103 can be integrally formed.
[0039] Thus, by utilizing the annular limiting structure 103, radial limiting rib 104, threaded hole post 105, and axial limiting buckle 106 to comprehensively limit and fix the bearing 200 in both the axial and radial directions, the bearing's anti-dislodgement strength is enhanced when it is dropped. In addition, installation can be completed simply by placing the bearing into the receiving space and screwing in the screws, making installation and disassembly easier and more convenient.
[0040] Please see Figure 5-8 , Figure 5 and Figure 6 These are perspective views of the bearing mounting structure of this utility model from different angles in two other embodiments. Figure 7 and Figure 8 Is the bearing installed? Figure 5 and Figure 6 The diagram shows three-dimensional views of the bearing mounting structure from different angles. Unlike the first embodiment, in the second embodiment, the axial retaining clip is removed, and the number of threaded hole posts 105 and corresponding screws 108 is increased. The threaded hole posts 105 are distributed approximately evenly along the circumference of the annular retaining structure 103.
[0041] In some embodiments, the annular limiting structure 103 may be integrally formed with the mounting shell 101 body 101a, or some or all of the radial limiting rib 104, threaded hole post 105, and axial limiting buckle 106 may be integrally formed with the annular limiting structure 103, or the annular limiting structure 103, the mounting shell 101 body 101a, and some or all of the radial limiting rib 104, threaded hole post 105, and axial limiting buckle 106 may be integrally formed. Of course, these components may also be installed or assembled into one unit in other ways.
[0042] It is understood that in other embodiments, the annular limiting structure 103 can be omitted. In this case, the diameter of the opening 102 is smaller than the diameter of the outer ring 201 of the bearing 200. The mounting shell 101 body 101a is arranged around the area of the opening 102 to support the bearing 200. The radial limiting rib 104, the threaded hole post 105, and the axial limiting buckle 106 are directly arranged on the mounting shell 101 body 101a around the opening 102. By providing the radial limiting rib 104 and the threaded hole post 105 on the mounting shell 101 body 101a, the mounting shell 101, the radial limiting rib 104, the threaded hole post 105, and / or the axial limiting buckle form the mounting position of the bearing 200. The radial limiting rib 104 abuts against the outer circumferential surface of the outer ring 201 of the bearing 200, and the axial limiting structure restricts the bearing 200 from moving away from the mounting shell 101, achieving a double limiting and fixing effect. The structure is simple and practical.
[0043] It is understood that screw 108 also includes washer screw, which contains washer. After the washer screw is screwed into the threaded hole 105a, the edge area of the washer extends beyond the threaded hole post 105 and abuts against the end face 201b of the outer ring 201 of the bearing 200 through the edge area of the washer, thereby limiting the bearing 200 in the axial direction.
[0044] Compared to existing technologies, the bearing mounting structure provided in this embodiment of the invention utilizes a ring-shaped limiting structure (or mounting housing body), radial limiting ribs, threaded hole pillars and screws, or, with the addition of axial limiting buckles, to comprehensively limit and fix the bearing in both the axial and radial directions, thereby enhancing the bearing's anti-dislodgement strength when dropped. Furthermore, installation is simpler and more convenient; the bearing is merely placed into the receiving space, and the screws are then screwed in.
[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
